scsih_pci_mmio_enabled(9)

✨ NAME ✨

okay so bestie, we're in the Kernel API Manual and the page is scsih_pci_mmio_enabled(9). The whole serve? scsih_pci_mmio_enabled is here to enable MMIO and dump debug registers. That's the assignment, and it ate. 💅

🌸 SYNOPSIS 🌸

the signature is giving blessed kernel API realness:

pci_ers_result_t scsih_pci_mmio_enabled (struct pci_dev *pdev );

🎀 ARGUMENTS 🎀

• pdev — pointer to PCI device. that's the one and only argument, bestie, and it's literally a pointer to a PCI device. 🫶

💅 SEE ALSO 💅
